Use this section of your notes to
write questions, make
connections, and sketch what
you are visualizing!
The Kinetic-Molecular Theory of Gases
A. The kinetic-molecular theory is based on the idea that particles of matter are always in
___________. For gases, this theory is based on the following _______ assumptions.
1. Gases consist of __________ numbers of tiny particles that are ______
_________ relative to their size. Most of the volume of a gas is _______________
_____________.
2. Collisions between gas particles and between particles and container walls are
__________________ collisions.
a. An ________________ collision is one in which there is no net loss of
energy.
3. Gas particles are in __________________, rapid, random ______________.
a. Gases therefore posses ____________ energy which is the energy of
______________.
4. There are no forces of ____________________ or ___________________
between gas particles.
5. The average kinetic energy of gas particles depends on __________________.
a. Kinetic energy is given by the following equation:
KE= ½ mv2
B. An ____________ gas is an imaginary gas that perfectly fits all the assumptions of the
kinetic-molecular theory.
C. A __________ gas is a gas that does not behave completely according to the
assumptions of the kinetic-molecular theory. The more __________ the gas molecules the
greater the deviation from ideal behavior.
The Kinetic-Molecular Theory of Gases and the Nature of Gases
A. ___________________. Gases do not have a definite ___________ or a definite
___________. They completely fill their container.
B. ____________________. Because the _______________ forces between gases is
insignificant, gas particles can easily slide past one another.
C. _____ ________________. The gas particles are very far apart in the gaseous state.
D. ______________________. During ________________________ particles that were
very far apart are crowded together.
E. _____________________ and ______________________.
1. Spontaneous mixing of the particles of two substances caused by their random
motion is called _____________________.
2. ____________________ is a process by which gas particles pass through a tiny
opening.
